Used GMC trucks for sale near Barnstable, MA

Excellent as always; second vehicle acquired from Marty's GMC

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I would like to say big Thankyou , The nice people of colonial Ford and especially Brendan smith for making my transactions simple , fast and efficient

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

What an amazing crew at McGovern! I am so impressed with how kind, thorough and helpful everyone is consistently every time! Highly recommend!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

as usual the service is amazing. I have used the same dealership for years

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Experienced, knowledgeable, customer oriented w a personable platform affording more confidence as a prospective customer!

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

No pressure sales, prices were on all vehicles in the lot, great buying experience. I found it easy dealing with the owners directly. Would definitely buy from them again.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

We Couldn't ask for better employees or service at a great dealership offering professional confidence and target for customer service and satisfaction. I've purchased numerous GMC/Buick products from them and couldn't be more satisfied.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Can't get better than Marty's! We purchased a new 2021 Acadia through Marty's this go-around and had the pleasure of doing business with Paul. Great sense of humor, but even better businessman. We showed him a great offer from a competing dealership up in NH, that every other local dealership around here told us was impossible to make. Paul disappeared for a few minutes came back and said I can match that! So happy with the car, and happy we got to continue our relationship with Martys.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Thankyou Colonial Ford after driving Toyota for the last 20+ years i made the change to Ford and love the safety features and fuel efficiency Thankyou Brendan smith and colonial Ford.

GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

Went in for an oil change. Customer Service was fast and polite. The Service time was fast for what seemed to be a pretty busy day there.

Small, local company. Great experience. Helpful and knowledgeable staff. Easy to work with. Follow up and follow through were great. Great vehicles to choose from.

Incredible customer focus. Had an issue with my 2020 Silverado. Had to drive from Wareham to Marlborough so I pulled in to Robertson GMC, never once believing that I would be able to continue. Within an hour they had it diagnosed and the part shipped for next day delivery. I was thrilled but was totally surprised when they offered me a rental to continue with my trip. They called the next morning and the truck was repaired by 10:00. I returned to pick it up and they had even washed and vacuumed it. Incredible customer support, especially the Service Advisor, Jim Morrill. What a pleasure it was dealing with Robertson GMC!

Courteous service and a capable repair staff. Even an around town vehicle if you are waiting.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

The folks at O?Hara are unfailingly polite, service is always done right the first time and at a fair price. Always a pleasant experience getting my Jeeps serviced.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Every department at Robertsons has knowledgeable employees that are extremely friendly and helpful. I have purchased multiple cars there and the process has been all around easy because of the employees. And the service department always gives updates if needed and has your vehicle done at the promised times

Missing a few things that could really make it better. Homelink for garage door isn’t offered? Doesn’t come with a receiver type hitch however what does comes with it is almost the same amount of steel. The phone charger doesn’t work quite right and they know it.

Both Mark & DJ made the car buying process easy. They were both professional and a pleasure to deal with. This is the fourth vehicle we?ve bought from them and will not consider buying from any other GMC dealer.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Had an amazing experience from start to finish with Carlos Alves. Very happy with my purchase. They are very upfront and honest. Whatever I was shown at time time we agree on the purchase was the same on my final paperwork.

Great service. Pleasant greetings. Timely Call backs when messages left. Accommodating, efficient and fair price for oil change and tire rotation. Travel the distance for good service.

I love my 2022 GMC Canyon Elevation. The V6 engine is great. Good gas mileage, even for the way I drive it! Great comfort and very stylish. All around, just a great truck.

buying a car is usually a lot of work, but i am happy to say this time it was a pleasure. I found the truck that was advertised on Cars.com looking better than i expected. I had no problem with the price and will gladly recommend RRR auto sales to friends and anybody for that matter. Can't wait to pick up my great deal! Thanks Guys!

Unbelievable how clean this used car is. If you didn’t know different, you would think is brand new! Very friendly staff! Wonderful purchase experience. Definitely recommend! Quick and easy purchase experience. No haggle. Used car was immaculate...looks brand new! Husband very excited for his new toy.
